What happens when a solid becomes a liquid?
a) it changes shape and volume
b) it changes volume but not shape
c) neither volume nor shape changes
d) it changes shape but not volume

Option (D)

When a solid becomes a liquid, It changes shape but not volume

Explanation:

When a solid is converted into a liquid, the shape of the liquid will changes allowing the tightly packed particles to expand and move freely and it conforms to shape of the container but the volume being fixed and definite.

The best example of this is melting of ice. When an ice cube is melted into water, the liquid state acquires the shape of the container in which it is kept and the volume remains fixed and constant.

it is the most commonly accepted one

a electronegativity decreases beacuse the size of nucleus is bigger.
